Not quite clear to me what your intentions are but I guess you want to make maps with custom textures looking more like a household rather than the classic industrial or street atmosphere AC's textures folder has to offer...
I suppose you could get a look there >>> CG Textures <<<, all those textures are free of charge but in case you want to publish one of these maps all you got to do is mention your sources in a readme.txt file (we never say that enough).
You probably also going to have to rework some of these textures so I suggest you read the >>> custom textures <<< section before, the AC docs are always useful when it comes to modding.
